  • Ages 18 to 85 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Males and females 18 to 85 years of age and in good general and oral health without any known allergies to commercial dental products;
  • Evidence of a personally signed and dated informed consent document indicating the subject has been informed of all pertinent aspects of the trial;
  • Willingness to use the assigned products according to instructions, availability for appointments and likelihood of completing the clinical trial;
  • Willing to adhere to the study requirements and restrictions;
  • Lower partial denture wearers who have a lower partial denture made for them as a part of a partial denture panel under study 14-I-098 (IRB # 1407637739) or who agree to wear their own pre-approved lower partial denture that can house both specimens on one side of their partial denture.

Who cannot join

  • Oral Examination Inclusion Criteria:
  • Normal salivary flow rate (stimulated and unstimulated flow of ≥ 0.8 mL/min and ≥ 0.2 mL/min, respectively) ascertained from the Screening visit;

Note: for persons who would otherwise qualify but whose lower partial denture needs repair, the individual may be listed as "pending". Once the partial denture has been repaired and adjusted to fit adequately for the subject to wear the lower partial denture 24 hours a day, the subject may be considered "qualified", complete their minimum 4 to 5 days washout period (of their own fluoridated toothpaste use) and continue with visit 2 in the study;
  • Absence of significant oral soft tissue pathology and dental caries, based on the dentist's visual examination and at the discretion of the investigator. Note: for persons who would otherwise qualify but who present at screening with dental caries requiring treatment, the individual may be listed as "pending". If the subject completes the restorative work within an acceptable amount of time, the subject may be considered qualified, complete their minimum 4 to 5 day washout period (of their own fluoridated toothpaste use) and continue with visit 2 in the study; and
  • Adequate oral hygiene (i.e. brush teeth daily and exhibit no signs of oral neglect).
  • Exclusion Criteria: Subjects presenting with any of the following will not be included in the trial:
Show all 24Show fewer
  • Are taking or have ever taken bisphosphonate drugs (i.e., Fosamax, Actonel and Boniva) for the treatment of osteoporosis;
  • Use of blood thinning medications that prohibit the safe conduct of a dental cleaning (*NOTE: Subjects who are taking blood thinners in which written verification is obtained from their physician indicating their PT/INR levels (anti-coagulation blood levels) are at an acceptable level to avoid serious complications, such as bleeding during dental cleanings, may be accepted into the study);
  • Suspected alcohol or substance abuse (e.g., amphetamines, benzodiazepines, cocaine, marijuana, opiates) in the past year;
  • Report allergy to products (Ferumoxytol or other drugs or specific ingredients) used in the study, a reported history of multiple drug allergies or known hypersensitivity to any iron products;
  • Scheduled for MRI for the head region within three months after study participation involving Ferumoxytol application;
  • Have a history of significant adverse effects following the use of oral hygiene products such as dentifrices and mouth rinses;
  • Use of antimicrobial agents/antibiotics whether prescribed or over-the-counter within two weeks prior to each treatment visit;
  • Presence of severe marginal gingivitis or moderate/advanced periodontitis based on the clinical examination and discretion of the dental examiner;
  • Subjects who during the study will receive dental treatment, which may affect their participation (i.e. oral prophylaxis). Emergency treatment will be allowed if necessary;
  • Those requiring antibiotic premedication prior to dental treatment;
  • Participation in a dental clinical trial involving oral care products within 30 days of randomization (Baseline Visit);
  • Self-reported pregnancy or lactation or intent to become pregnant during the study period;

About this study

To evaluate the effects of a clinically approved and commercially available iron oxide formulation Ferumoxytol (Feraheme®) to control cariogenic biofilms and enamel demineralization. This study will be testing topical application of Ferumoxytol extra-orally using a standard in situ biofilm demineralization model.

Read the detailed description

This will be a randomized, crossover, single blind in situ study with three test periods utilizing 16 subjects. The subjects in this study are lower partial denture wearers who have already had a study partial denture made for them as a part of a partial denture panel under 14-I-098 (IRB # 1407637739) or who will wear their own lower partial denture which was previously approved as part of the panel. The study partial dentures or personal partial dentures can house the specimen holders in two hollowed out areas of the buccal surface of two posterior denture teeth. The subjects will wear the lower partial dentures with enamel specimens in place for three consecutive 14-day study periods.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Biofilm Analyses-cell viability

    The effect of the treatments will be analyzed in terms of biochemical and microbiological composition of the biofilm formed. Colony forming unit (CFU) will be used to quantify the number of viable cells in biofilms.

    Measured: 14 days

  2. Biofilm Analysis-extracellular polysaccharides

    Biofilm EPS amount (weight in milligram) will be determined using colorimetric assay.

    Measured: 14 days

Secondary outcomes (1)
  1. Assessment of Enamel Demineralization by Means of Surface Microhardness Test (SMH)

    The surface microhardness (SMH, length in micrometer) test will be used to assess changes in the mineral status of enamel specimens.

    Measured: 14 days

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Ferumoxytol/Hydrogen peroxide, Hydrogen Peroxide and Water in people with Dental Caries, run by University of Pennsylvania at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Biofilm Analyses-cell viability (time frame: 14 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03678012, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2018.
